A hybrid fusion-fission reactor for the transmutation of spent
nuclear fuel
is being developed at Georgia Tech. The Subcritical Advanced
Burner Reactor
(SABR) is a 3000 MWth sodium-cooled, metal TRU-Zr fueled fast
reactor driven
by a tokamak fusion neutron source based on ITER physics and
technology. We
are investigating the accident dynamics of SABR's coupled
fission, fusion
and heat removal systems to explore the safety characteristics of
a hybrid
reactor. Possible accident scenarios such as loss of coolant mass
flow
(LOFA), of power (LOPA) and of heat sink (LOHSA), as well as
inadvertent
reactivity insertions and fusion source excursion are being
analyzed using
the RELAP5-3D code, the ATHENA version of which includes liquid
metal
coolants.
